Justified Gallery object isn't installed 
Autore: James A F.I have purchased the Justified Gallery and have been using it successfully for at least 2 years. Now my project refuses to open and I get the message attached.
I have searched the Website X5 site to learn how to reinstall the object, but have found nothing.
I have recently moved my Website X5 work from an old Windows 10 computer to a new Wndows 11 computer. I also moved the SSD drive that contained my Website X5 work into the new computer and have continued to work from that SSD drive on the new computer.
It seem to be a gradual decay of the Justified Gallery object. It was showing some problems, but still working and I was still able to open the project until this complete loss of function.
Please help, as I can not get any work done now. I do not have access to the project.
Have you already tried reinstalling the object? The best thing to do is to create a new project and install the missing object via object management. You can find the object management when editing the template or editing a page when you click on the button

Well thank you my friend, for your prompt reply. Your suggestion worked. So simple.
In a new project I clicked that "add objects" icon, uninstalled the Justified Gallery object, then installed it.
Vielen Dank, mein Freund, für deine schnelle Antwort. Ihr Vorschlag hat funktioniert. So einfach.
In einem neuen Projekt klickte ich auf das Symbol "Objekte hinzufügen", deinstallierte das Objekt "Justified Gallery" und installierte es dann.
